OCULUS Centerfield® 2

Perimeter

Thanks to its ergonomic design, user-friendly program navigation and ease of operation, the Centerfield® 2 Perimeter has proven itself to be an invaluable instrument in the Occupational Health area. The unit performs static perimetry up to 70° eccentricity. It also meets the requirements of the German Ophthalmological Society’s (DOG) Road Traffic Commission for conducting visual field testing in accordance with the regulations for the issuance of driver’s licenses and the Guidelines G25 and G41 issued by the German Institute for Occupational Health and Safety.

Threshold Noiseless Trend (TNT) Progression Analysis

TNT provides a quantitative, statistical analysis of the visual field examination results conducted over time. For follow-up purposes, the software uses the visual field results and patient's threshold values supplied by 30-2, 30x24 or 24-2 grids over the entire examination period. TNT uses a specific filter to reduce the fluctuation range of the threshold values and to perform a consistent trend analysis. In conjunction with the fast SPARK strategy, the sensitivity of detecting progression of early stage glaucoma is greatly improved.
